WASHINGTON (Reuters) – U.S. President Donald Trump said on Wednesday that John Bolton, dismissed a day earlier as national security adviser, had been a “disaster” on North Korea policy, “out of line” on Venezuela, and did not get along with important administration officials.

Trump said Bolton had made mistakes, including offending North Korea’s leader Kim Jong Un by demanding that he follow a “Libyan model” and hand over all his nuclear weapons.

“We were set back very badly when John Bolton talked about the Libyan model … what a disaster,” Trump told reporters at the White House.

“He’s using that to make a deal with North Korea? And I don’t blame Kim Jong Un for what he said after that, and he wanted nothing to do with John Bolton. And that’s not a question of being tough. That’s a question of being not smart to say something like that.”
